The best minds, even in the religious world, admit that in the material
nature there is no evidence of what they are pleased to call a god.
They find their evidence in the phenomena of intelligence, and very
innocently assert that intelligence is above, and in fact, opposed to
nature. They insist that man, at least, is a special creation; that
he has somewhere in his brain a divine spark, a little portion of the
"Great First Cause." They say that matter cannot produce thought; but
that thought can produce matter. They tell us that man has intelligence,
and therefore there must be an intelligence greater than his. Why not
say, God has intelligence, therefore there must be an intelligence
greater than his? So far as we know, there is no intelligence apart
from matter. We cannot conceive of thought, except as produced within a
brain.
